The Stone Age is the earliest period of human history. The Stone Age is typically divided into three periods: the Paleolithic (or Old Stone Age), the Mesolithic (or Middle Stone Age), and the Neolithic (or New Stone Age).

Before the Stone Age, there was the Lower Paleolithic, also known as the Early Stone Age, which began around 2.5 million years ago and ended around 300,000 years ago. During this time, early humans were using simple stone tools and were primarily nomadic hunter-gatherers. They were also developing the ability to control fire and make basic shelters.

Before the Lower Paleolithic, there was the Pliocene Epoch which began around 5.3 million years ago and ended around 2.6 million years ago, during this period we have the first evidence of human like species, like the Australopithecus, and the first humanoids like the Homo habilis.

It is important to note that the human species as we know it today (Homo sapiens) only appeared around 300,000 years ago, and that the Lower Paleolithic period is when the first human-like species began to use stone tools.

Chemical name of a drug describes a medications' generic name as it's the name of drug without any advertising.

When a new chemical entity (NCE) is created, a chemical name is assigned. The medicine is hardly ever identified by its chemical name in clinical or commercial contexts because it is a scientific name based on the chemical structure of the substance (6-thioguanine, for example).

A substance used to treat, diagnose, or prevent disease is known as a medication. A significant area of medicine is drug therapy, which depends on the growth of pharmacology science and the administration of pharmacy.

The continuous training strategy incorporates the modes of Uniform Continuous (UC), Varying Continuous (VC), and Progressive Continuous (PC).

Continuous training typically includes aerobic exercise such as running, cycling, swimming and rowing. These activities work large muscle groups in repetitive movements over long periods of time.

Continuous training, also called continuous training or steady-state training, is any type of physical training that involves non-resting activity. Marathons and cross-country are classic examples of continuous training methods. Heart rate is 140-160 beats per minute. Exercises should take no less than 30 minutes and may take up to 2 hours or more. Activities include running, walking, and cycling.

The results of this study showed that both high-intensity training and sustained endurance running lead to improved aerobic performance.

To determine a person's blood type and the related antibodies, a forward and a rear blood type would need to be done. In a forward blood type, red blood cells are assayed to confine their face labels and the person's blood type. The blood cells are treated with given blood- type antibodies. In this, a response would indicate the presence of the specific blood type marker. While with the rear blood type, the responses would indicate the presence of antibodies in the tube.

Immunoglobulins( Ig) are Y- shaped proteins, called antibodies, that are made by tube cells. There are 5 types of immunoglobulins – IgG, IgM, IgD, IgA and IgE.

A person basically inherits a gene from his each parent. But, his blood type may not be the same as his parents. For illustration If you inherit an A from one parent and an O or A gene from another parent, you'll have type A blood.

An example of a static stretch is a seated forward bend, where you sit on the floor with your legs straight out in front of you and then reach forward to touch your toes.

A dynamic stretch, on the other hand, is a stretch that is performed by moving through a range of motion. An example of a dynamic stretch is a leg swing, where you stand facing a wall and then swing one leg forward and back in a controlled motion.

2- Depending on my current level of flexibility, I would maintain and improve my level of flexibility by stretching regularly. An example of my current weekly stretching routine would include stretching for 15-20 minutes every day, focusing on different areas of the body such as my legs, arms, back, and shoulders. I would start with some dynamic stretching to warm up my muscles, then move on to some static stretching to hold the stretch for 15-30 seconds. I would also include some yoga poses and PNF stretching to improve my flexibility. If I don't have a current weekly stretching routine, my weekly routine should include stretching for at least 15-20 minutes every day, focusing on different areas of the body and incorporating both static and dynamic stretching. It's also important to make sure to stretch after exercising, when muscles are warm, to make stretching more effective.

Drowsy driving causes 21% of all fatal collisions. About 168 million adult drivers, or 60% of all drivers, admitted to driving while fatigued in the previous year. In 2012, it was discovered that younger drivers (16 to 24 years old) were nearly twice as likely to be driving while fatigued than their older counterparts (40 to 59 years old) at the time of an accident. In that year, these younger drivers also admitted to driving while fatigued and dozing off behind the wheel.
